1. Why my device laged after saving a mode?
One night, a user contacted me about an issue that came up after installing the 2.1 version of One Power Guard. He said his device lagged in Standby mode. I told him that we can work together to solve his problem. After work, I went back to my dorm. I started to write a test interface for him and 1.5 hours later, we started testing. He began to test my ten-step interface – each step ran well. But the issue was not resolved. I asked him to select AI mode – his device lagged. What we found is that his device did not support changing CPU frequencies. So my judgment was that this was an I/O scheduler issue, it was set to “CFQ”. I asked him to try changing his I/O scheduler. (His Rom Only support CFQ and Noop). He changed to “Noop” and the lag went away – issue resolved!

2. What is a safe clean?
Android has a process management mechanisms, when a process is killed by task killer app, the android system will determine whether the process will be run again, if it is, the process will restart again, the killed process will repeat restart, cause increased power consumption. “Safe Clean” is a different type of Task killer. It will safely kill which apps have started consuming the battery and kill some processes cleanly. I hope this guide helps shed some light on a murky subject going on in the Android world. Now you know and knowing is half the battle. Now, go uninstall that task killer off your phone.

3. Why it run in the background?
We have a “safe clean” technology to kill drain processes, it need to run in the background and periodically clean some drain processes.

4. How to fix “initializing” loading? Does it not work?
If this app gets stuck at “Initializing”, please check this problem with SuperSU or Superuser not allowing it root access. and just keep one of SuperSu and Superuser, or reinstall SuperSu or Superuser by recovery.

6. Does OnePowerGuard Pro change the kernel parameters? I am very worried about that.
Yes. OnePowerGuard Pro changes kernel parameters, but don’t worry. For example: when you buy two different phones whose kernel are not the same. Google Android also changes Linux kernel parameters. Every producers revise its own Android kernel. If you are a geek, you can changes some of the initialization files and put them into init.d folder. When you root your phone, you have already changed your Android kernel.
If you are worried about that, just uninstall OnePowerGuard Pro and reboot your phone.

7. Why my device not support CPU frequency settings?
OnePowerGuard Pro gets two files values. (/sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq and /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq value. If their are missing), if they are not exist, it meant that your devices doesn’t support. please contact the kernel’s distributor.

8. Why is there no “ondemand” “powersave” Option?
Because the kernel does not support, Many custom kernels have customized governors written by the community. For explanations of these, please contact the kernel’s distributor.

9. Why my battery is discharging while connected to my computer?
USB will wake up your device or your device has been aging.

10. How to restore the original parameters of your phone
All modes optimize your kernel, CPU, network, SD card, memory, etc, if you don’t want to use this app, just uninstall it or uncheck “Set On Boot”, and then restart your phone, everything will be restored the original parameters.
